Mission Hills residents' attempt to postpone construction of a housing project on the golf course near their homes by forcing an analysis of the land for arsenic content suffered two setbacks in recent days.

The Illinois Appellate Court on July 13 refused to overturn a Cook County judge's denial of a temporary restraining order on Red Seal Development's "Provenance" project, according to Bethany Krajelis, the state's higher-court spokeswoman. And a request by two state lawmakers to voluntarily enter an IllinoisEnvironmental Protection Agencyexamination of the land was rejected by Red Seal, one of those legislators, Rep.Elaine Nekritz, D-57, said Monday.

"They basically said that they would comply with all laws and regulations as regards to dust control," Nekritz said. She and Sen. Julie Morrison, D-29, had made the request in a joint letter July 8.

"We're trying to figure out if there's anything else to pursue at this point," Nekritz said.
